- This invention relates to reproducing apparatus whereby reproductionsmay be made on the same scale as the original by contact printing or ondifferent scales by optical means.

An object of the present invention is the production of a combinedphotographic contact printer and a camera provided with a lens orrectifier to assemble in a single apparatus the units necessary forprinting and reproduction of documents or other papers on the same ordiilerent scales. The prints may be made on glass, negatives, films orsensitized papers and the apparatus permits the examination andinspection of the negatives or documents as desired by reflection or bytransparency. A further object of the invention is the provision of acontact printer and a camera with the optical axis of the cameraarranged substantially in alignment with the axis of the printer.

Still another object is to provide .a camera with a lens mounted on theexterior of the camera and means whereby the lens may be brought intoalignment with the printing frame for focusing the object to bephotographed.

In the accompanying drawings we have shown several forms oftheinvention. In this show- Fig. l is a side elevation of the apparatus,parts being shown in section;

Fig. 2 is a plan view;

Fig. 3 is a front elevation of the camera supporting means with thecamera carried thereby, the camera being shown inv section;

Fig. 4 is a view of the moving picture camera at right angles to Fig. lwith the side of the camera open;

Fig. 5 is a longitudinal, sectional view of the feed guide and presserframe; and

Fig. 6 is a detailed view of the film feeding mechanism.

In the form of the invention shown, the ap paratus consists of a cabinetI, in which is arranged a lighting box or compartment 2. A plurality ofwhite lamps 3 is arranged in the box and one or more red or orange lamps4 may also be arranged in the box. The side walls of the box areprovided with slides i for the reception of one or more plates or masksi of frosted glass. A clear glass 1 is placed on top of the box and isadapted to receive the negative to be reproduced by contact printing.The sensitized paper, film or layer of sensitized material on glass isarranged over the negative in the usual manner ,being inserted throughan opening 0 in the top of the cabinet. A hinged (not shown) may beconnected to the switch Ill.-

The top of the cabinet is provided with an opening for the reception ofa vertical column l3. This column is provided withrack teeth [4 adaptedto engage a pinion l5 located within the cabinet. The pinion is mountedon a shaft l6 which is provided with a hand wheel oricrank II on theoutside for operation of the shaft. Standard l3 passes through a sleeveI8 which is mounted on the top of the cabinet and this sleeve carries abrake I! which engages the standard. A set screw 20 is also provided forlocking the standard in adjusted positions.

A pair of vertical arms 21 are mounted on the top of the cabinet, eachof which supports a horizontal arm 2' carrying lamps or projectors 29.The arms 28 are vertically adjustable and the lamps may also be adjustedon these arms so as ,to properly illuminate that part of the top of thecabinet which is situated in the field of the lens. when the projectorsare not in use during printing the lamps may be swung out of the way.The lamps are controlled by a switch ll mounted on the top of thecabinet.

A supporting plate II is then mounted on top of the post or standard l3and forms a support for the camera. The support 2| carries a dovetailplate 33 (Fig. 4) which is adapted to receive a U-shaped support orcamera holder 35. The plate 33 and the holder 35 are provided with theinterlitting dove-tail 34 so that the holder 35 is mounted on the plateto permit sliding without play. Adjacent the front of the plate 33 anopening is provided beneath which is arranged a lens it. This lens ismounted on a fitting 31 carried by the plate 33 and is adapted to beadjusted to regulate the axial displacement of the lens. A handle 3. isprovided for adjusting the lens 36 for focusing.

The camera holder 35 is also provided with an opening ll of the size ofthe opening in the plate and a window ll in the camera 42 is arranged inalignment with this opening when the camera is mounted in the holder. Asshown in Fig. 4, the camera. consists of three compartments. A freelymounted shaft 43 is mounted in one compartment and is adapted to receivea take-up reel 44 for the film. A toothed drum 45 is mounted on a shaft46 below the reel 44. A pressure roll 41 is arranged adjacent the .drumand is controlled by a spring 48.

In the opposite compartment a similar, shaft 49 is adapted to receive areel 50. containing the unexposed film and from the' reel 50 the filmpasses over freely mounted rollers and 52 mounted on shafts 53 and 54. Apressure frame 55. is arranged in alignment with the window or opening4| in the camera frame.

The central compartment of the camera houses and arranged on the take-upreel in the usual manner. With the camera in the position shown in Fig.3 of the drawings, the camera window or opening 4| is out of alignmentwith the lens 35. The camera is provided with focusing means carried bythe U-shaped frame or camera holder 33 and consisting of a support 62carrying a prism lens 63, the lower surface of which is frosted. Withthe parts in the position shown in Fig. 3 of the drawings and with thecamera holder 33 engaging stop 64, the lens 63 is arranged above thelens 36 to permit examination of the projected image and proper focusingof the camera. After the camera has been focused, the camera holder 33is moved to the left in Fig. 3 of the drawings until it engages stop 6|at which time the camera window 4| is then in alignment with the lens 36and the camera properly focused for the taking of a picture.

The actual photographing is carried out in the usual manner by operationof the shutter 39. Operation of the shutter 33 is effected by means ofa' flexible cable release 65, the operating head of which is fastened tothe casing 35 by member 35. The control button 61 of the shutter cableis located in the path of a handle 68 (see Fig. 6). This handle rotatesfreely on the film feeding drum 45 and is provided with a pawl 59projected by spring III which engages the teeth of a ratchet 1| keyed tothe shaft 45. Shaft 45 is provided with a grooved pulley I2 and shaft 43is provided with a similar pulley 14. A belt I3 extends over thesepulleys.

In operation the opening of the lens is therefore caused by operation ofthe handle 68 coming in contact with the shutter release button 81. Whenthe handle is raised to its initial position pawl 53 engages one of theteeth of ratchet II and drives the drum to feed the film a properdistance for taking up the previously exposed film. The travel of handle68 may be controlled by a stop 15 so that the proper amount of film isfed to the take-up reel 44 following each exposure. The window of thecamera is provided with a removable glass 11 (see Fig. 5) serving as asupport for the film. The presser frame 55 is likewise provided with aremovable glass I8 to clampthe film against the glass 11 and prevent itfrom buckling. This arrangement also permits projection of. recordedfilms by means of the projecting device carried by the camera. When thedevice is so used, metal plate 19 which is arranged over the pressureframe and retained in position by springs 80 is removed. The film maythen be fed in the usual manner and illuminated by the lamp 56.Condenser lens may be properly focused by sliding the sleeve or casing58 to the dotted line position shown in Fig. 4.

In photographing negatives to be reproduced a removable frame 32(Fig. 1) can be fitted into the opening 8 of the cabinet and providedwith a glass on which the negatives may be placed.

From the foregoing it will be apparent that the apparatus may be usedfor printing positive films fromnegative films by use of the contactprinter or it may be used for printing by simultaneously winding thenegative film and the unexposed film on reel 50 and feeding them throughthe camera and illuminating them by the projectors 29. The images of thefilm may also be projected on to the table I for inspection and thedevice may be used for reproducing images on photographic paper, film orthe like of any desired scale.
